Coupling tank in boiler system
The function and working principle of coupling tank in bolier floor heating system
01 Description of the problems inthe construction of floor heating
According to the actual use of floor heating, we often hear the user to reflect, The power design of the boiler and the heat load design and the system design are no problem, but some local rooms are not hot. These problem are mainly reflected in the larger area or duplex housing. In view of this problem, the reasons are as follows: The circulating pump power of the boiler itself is small, so the pump lift is not enough. In the small area, the hot water in the system can be driven to better circulation, but when the area is large, due to the large amount of water circulating in the system, so that some distant loops cannot be well circulated, resulting in poor local heating effect.
Description of the problems inthe construction of floor heating
02 The main function of the coupling tank
Solve the problem of some low temperature area caused in large system: effectively improve the problem of low temperature caused by improper selection of problem pipelines; Solve the problem of boiler supply several floor; Solve the inconsistent flow rate and temperature between floor heating and radiator mixed installation
The mixing tank can make the primary circulation and the secondary circulation relatively independent operation
The flow of each loop system only depends on the base of its own water pump characteristic parameter, to avoid the interference caused by the water pump in series, using the mixed water, secondary loop system only work in its own water pump open, when the secondary circulating pump shut down, all from a circulation pump flow pressure within the mixing tank bypass back to primary system.
The most prominent characteristic of the coupling tank is to ensure co-existence and operation of a constant flow system and a variable flow system, effectively protect the system safety of independent heating equipment, and improve the operation efficiency of heating equipment, energy saving and consumption reduction: provide customers with satisfactory heating effect.
Installation of coupling tank
03 Installation of coupling tank
The installation of coupling tank should pay attention to two points
1. it should be installed vertically
2. when connecting to the system, hot pipes (such as supply pipes) should be connected to the upper part, and cold pipes (such as return pipes) should be connected to the lower part. The upper part of the coupling tank is equipped with an air vent, and the down part is equipped with a drain ball valve. The coupling tank is insulated.
The coupled tank balances the flow of the system, if without coupling tank, just put the pumps in series in the system, the water flow are not increase, just increase the lift, but water flow speed and pressure increases, This reduces the life of the pump and the boiler also frequently started, ont only temperature don't increase but also waste of energy
04 Configure the coupling tank specification
In large area or multi-storey housing, the floor heating area of more than 100 square meters and Radiator more than 6 pieces must be equipped with a secondary circulation pump, and the pump flow/head shall be calculated and customized by the designer.
